SPECIFICATION formingpart of Letters latent No. 686,220, dated November5, 1901.

Application filed December 29, 1900. Serial No. 41,490. (No model.)

To aZZ whom, it may concern: 7

Be it known that I, CARL GABRIELSON, a citizen of the United States, anda resident of Greenville, in the county of Hudson and State 5 of NewJersey, have invented certain new and useful Improvements inType-\Vriting Machines, of which the following is a specification.

This invention relates to means for indicatl ing the position of thepaper-carriage, and is in the nature of an improvement upon theconstruction for which Letters Patent were granted to Jacob FelbelOctober 30, 1900, No. 660,988.

The main object of the present invention is to enable the use of largerand more easily read numbers and at the same time to put the numberingdevices into a more compact form, so that they may not occupy room thatmay 20 be needed for other portions of the type-writer mechanism andalso so that the numbers may be read through a sight-hole provided inthe top plate, where they fall more readily under the operatorsobservation.

In carrying out my invention I coil a series or column of numbers aroundthe periphery of a wheel 01' drum and provide a sight-hole through whichonly that one of said numbers which corresponds to and henceindicatesthe position of the carriage can be seen by the operator.Thesight-holeisimmovable,while the drum is caused to both rotate andslide upon its bearing, thereby bringing the spirally-arranged numbersthereon successively opposite the sight-hole, so that the operator mayat any time inform himself of the exact position of the carriage bymerely glancing at the number within the sight-hole.

My invention consists in certain combinations of devices and features ofconstruction, all as will be more fully hereinafter set forth, andparticularly pointed out in the concluding claims.

In the accompanying drawings, Figure l is a sectional elevation takenlongitudinally of a front-strike type-writin g machine, showing myimprovements applied thereto. Fig.

the machine, showing a sight-hole and a nu mber appearing therethroughwhich tells the position of the carriage. Fig. 5 is a sectional plantaken below the top plate of the machine and showing the number-wheeland connections.

In the several views parts are omitted or broken away to more clearlyexhibit the invention, and similar parts are designated by similarnumerals of reference.

1 designates the rectangular baseof the machine, 2 corner-posts risingtherefrom, and 3 a top plate supported upon the posts. A reciprocatorycarriage 4, bearing a platen 5, slides in letter-space direction uponrails 6, which are fixed upon brackets 7, rising from the top plate. Arack 8 upon the carriage meshes with a pinion 9, which is connected to aletter-feeding escapementwheel 10. The carriage is propelled by a springdrum or barrel 11, which is connected thereto by a strap 12 and which ismounted upon a bracket 13, depending from the under side of the topplate. Type-bars 14 are pivoted at their rear ends in a segment 15 andstrike upwardly and rearwardly against the platen. The typebars areoperated by means of links 16, bellcranks 17, and key-levers 18, towhich said bell-cranks are pivoted. The key-levers are pivoted at theirrear ends upon a fulcrumrod 19 and are provided with keys 20 andreturning-springs 21. Beneath the key-levers is supported a transversefulcrum-rod 22, which is engaged by the forked lower ends of all thebell-levers 17. Upon said rod 22 is hinged a frame 23, which supports auniversal bar 24 and is connected bya vertical link 25 to the horizontalarm of a dog-rocker,which is pivoted in said bracket 18 and whoseupright arm 26 carries a feeding-dog 27 and a detent-dog 2 Areturning-spring 29 is provided for the dog-rocker and serves also tohold the universal bar 24 normally up against the key-levers. A ribbon30 is carried by spools 31, which may be rotated in any suitable manner.A release-key 32 may be provided upon the carriage, said key being fixedupon a forwardly-extending arm 33 of a bail, the latter being hinged tothe carriage-frame at 3% and comprising said rack 8. Upon depression ofsaid release-key the bail swings upon the hinge or pivots 34 and therack is lifted out of engagement with the pinion 9, whereupon thecarriage may be slid rapidly in either direction.

The drum, which indicates the position of the carriage, is designated as35 and is arranged vertically upon a horizontal shaft 36, mounted inlugs 36, depending from the top plate. A rotary movement is transmittedto said shaft from the carriage-driving drum 11 by means of a train ofgearing, which comprises a large spur wheel 37, secured, by means ofstuds 38 and screws 39, upon the front vertical face of saidspring-barrel 11 and in mesh with a pinion 40, which is fixed upon therear end of a forwardly-extending horizontal shaft 41, the latter beingjournaled in lugs 42, which depend from the top plate, and carrying atits forward enda bevel-pinion 43, which meshes with a bevel-gear 44,made fast upon said shaft 36. The shaft 41 is parallel with the axis ofthe spring-barrel and at right angles to the shaft 36, to which the drumis splined at 45, so that it is caused to oscillate during the back andforth endwise rectilinear travel of the carriage. The drum mayprojectupwardly through an opening 46, formed in the top plate 3 and may becovered by a cap-plate or shield 47, the latter havinga sight-hole 48.The numbers, one for each letter-feeding movement of the carriage, arearranged in a single column 35", which extends spirally or coils morethan once around the periphery of the drum. By means of the describedgearing t he drum is given acomplete revolution during about one-half ofthe endwise' travel of the carriage in either direction, or, in otherwords, about thirty-seven stepby-step letter-spacing movements of thecarriage causeacomplete revolution of the drum. To the end that anynumber in the spiral column may be brought beneath said sight-hole Iform upon the drum a spiral groove or worm 49, said groove preferablybeing arranged upon the periphery in alternation with the column offigures, and in engagement with said grooves I provide a fixed pin 50,which projects downwardly from the cap-plate 47. The pin cooperates withthe groove to cause the drum when turned by the described connections toworm or move in a spiral direction, the spline 45 permitting thenecessary sliding movement upon the shaft 36 and the drum beingpreferably hollowed, so as to telescope the gear 44. The nu mbers are sospaced in the column that successive step-by-step movements of the dru mbring successive nu mbers opposite the sight-hole, while the pitch ofthe groove 49 is the same as that of the column of numbers, so that saidcolumn always registers laterally with the sight-hole. The opening 46and cap 47 are made large enough to accommodate the endwise or lateralmovement of the drum.

In the operation of the machine a type-key 20 is depressed, vibratingits lever 18 downwardly and, through the bell-lever 17 and link 16,swinging the type-bar 14 to the platen to make an impression of the typeupon the paper arranged thereon. Upon release of the finger-key frompressure said parts are returned to normal position by spring 21. Duringthe reciprocation of the lever 18 the dogrocker is caused to vibrate bymeans of the described connections, and the escapement devices permit anadvance movement of the carriage toward the left in the usual mannerunder the influence of the spring-barrel 11. The movement of the latteris communicated by gears 37 40, shaft 41, and gears 43 and 44 to theshaft 36 and drum 35 thereon, which accordingly is given a combinedrotative and endwise movement, so that the next higher number thereon isbrought into view at the sight-opening 48. As the operation ofdepressing the keys is repeated the numberdrum is rotated step by stepin a spiral path, eachtimepresentinganewnumber,so that the operator whenwishing to ascertain the position of the carriage needs only to glanceat the number which is visible at the time through the opening 'orsight-hole in or upon the top plate. Upon the completion of the line ofwriting the carriage is returned by the operator to begin a new line,and through the connection 12 the spring-barrel is rotated re- Verselyto rewind the spring therein. By means of the described positiveconnections to the spring-barrel the number-drum 35 is also wormedreversely, so that when the carriage reaches its normal starting-pointfor a new line the character 0 or zero appears through the sight-hole48. If the carriage should be arrested at any point during its returnmovement or during a rapid movement thereof in letter-space directionwhen 'released from the control of the escapement devices by the key 32,the number which appears through said sight-hole at once informs theoperator of the exact position of the carriage. Thus the difficulty ofmentally calculating said position by means of graduations, line, ormarks upona carriage-scale is wholly avoided, as well as the constantliability of misreading the scale, and consequently imprinting theletters at a wrong point in the line of writing. By the use of therelease-key and the number-wheel the carriage can be adjusted instantlyto any desired position without possibility of confusion, and the workof the operator is thereby greatly facilitated. It will be understoodthat the spur-wheel 37 makes about one complete revolution during thewriting of a line. The diameter of the pinion 40 is about onethird thatof said spur-wheel, so that the bevel-pinion 43 revolves three times ateach revolution of the spur-wheel 37. The bevelgear 44, however, is oflarger diameter than the pinion 43, so that the rotative speed of thenumber-drum is but twice that of the spur-Wheel 37. The diameter of thenumberdrum is, however, considerably more than one-half the diameter ofthe spring-barrel,

ICC

and the movement of the peripheral or numbered portion of the said drumis hence considerably in excess of the corresponding movement of thecarriage. I employ the described motion-multiplying gearing between thecarriage and the number-drum for the purpose of enabling large figuresto be placed upon the latter, so that they may be easily read. Thebevel-gears 43 and 44: may be made of equal diameter, if desired, andthe column of numbers extended thrice around the drum, the worm 49 beinglengthened accordingly.

It will be observed that the oscillatory or back and forth wormingmovements of the number-drum correspond with and are governed by therectilinear reciprocatory move ments of the carriage in oppositedirections, and that said drum is controlled by the same step-by-stepfeeding devices as the carriage. It will also be noted that I haveprovided a drum with a column or series of whole numbers arrangedspirally thereon in numerical or consecutive order and corresponding tothe feeding movements of the paper-carriagethat is to say, the firstnumber denoted by said wheels is O to agree with the normal position ofthe carriage, and the last number denoted thereby is, say, 74 to agreewith the extreme left-hand position of the carriage.

Changes in construction and arrangement may be made within the scope ofthe invention. It is not essential that the numberdrum be arrangedvertically or at right angles to the spring-barrel 11 so long as thenumbers thereon are presented in their natural position to the eye ofthe operator. Viewed in one way my invention may be regarded ascomprising a plurality of columns of numbers arranged around a wheelcom.- bined with means for moving the wheel transversely as well asrotatively. It is not essential that said transverse movementbe securedin the described manner, although I prefer to use the details ofconstruction herein specifically described.
